HOG-OILER.

Application filed June 1, 1915.

To allwhom it may concern Be it known that I, HARRY D. DUCKHAM, a citizen of the United States, and resident of Kenton, in the county of Hardin and State of Ohio, have invented certain new and useful Improvements in Hog-Oilers, of which the following is a specification.

The main object of my invention is to provide a 110g oiler in which the rubbing surface is automatically oiled and in which the supply of oil to the rubbing surface is discontinued after a few drops have been supplied thereto, no matter how long the animal continues to rub against the device.

A further object of myinvention is to provide a device of inexpensive but durable con struction which shall be positive in its action.

My invention consists'in the construction, combination, and arrangement of parts as hereinafter more fully set forth and pointed out in my claims, and illustrated in the accompanying drawings forming a part of this specification, in which like reference characters indicate like parts.

Figure 1 is a front elevation of my hog oiler. Fig. 2 is a vertical section on the line 2-2 of Fig. 1. Fig. 3 is a horizontal section of the supporting bracket taken on line 3-3 of Fig. 2. Fig. A is a rear elevation of the device. Fig. 5 is a perspective view of the 1 rubbing bar.

Referring to the drawings, a bracket A, comprising a front 1 and sides 5, and having attaching ears 2 and 3 formed integral there- I with, is secured to a building or post by suitable screw fastenings. A shelf 6 formed at the top of the bracket, supports an oil reservoir 7, from the bottom of which projects a spout 8, which extends below the shelf through an opening therein. A curved trough 9, having a discharge spout 10 in its front wall, is pivotally suspended by suitable brackets 11 below the reservoir spout, so that the spout projects within the trough. An opening 16 is formed in the bracket A, and rearwardly extending supporting brackets are formed on each side of this opening as shown in Fig. 3. A lever 12, having a weight 13 on its lower end is pivotably mounted on the brackets 15, by lugs 14: formed on each side of the lever. On the upper end of this lever is a finger 17, adapted to engage a lug 18 on the bottom of the oil trough 9, when the lever is swung Specification of Letters Patent.

in the direction indicated by the arrow in Fig. 2.

A rubbing bar 13, suitably corrugated or roughened on its face as shown at 19, is ournaled on a shaft 20 supported by the bracket A at the front of the device below the oil reservoir. The top of the rubbing bar is curved rearwardly as shown at 21, in order to guide the oil discharged from the oil trough to the face of the rubbing bar. A finger 22 on the rubbing bar extends rearwardly through the opening 16 in the bracket A, and presses against the lever 12, so that when the rubbing bar is swung back by the pressure ofan animal rubbing against it, the lever will be swung as indicated by the arrow in Fig. 2. The rubbing bar is normally held in a vertical position by a coil spring 28 interposed between it and the bracket A, and held in position by lugs 21 and 25 formed on the bracket and rubbing bar respectively.

A hook 26 on the rear of the rubbing bar and extending through an opening 27 in the bracket, is adapted to engage the edge of the said opening to limit the forward move ment of the bar. A shoulder 28 on this hook, is adapted to abut against the front of the bracket A, to limit the rearward movement of the rubbing bar. The rubbing bar is guided in its movement by outwardly projecting guides 29 and 30 formed on the lower part of the bracket A.

The operation of the device will be readily understood. The oil trough will be fed through the spout on theoil reservoir maintaining the oil level on a line with the discharge spout 10. An animal rubbing against the bar 13 will swing it back, and thereby tilt the oil trough by the finger 17 pushing against the lug 18 as previously explained. This will discharge a few drops of oil onto the rubbing bar. As soon as the finger 17 is swung past the lug 18, the trough will swing back to a level position thus cutting oif the supply of oil. When the animal leaves the device the rubbing bar and the lever 12 will be swung back to a vertical position by the action of the spring 23 and weight 13 respectively.

It will thus be seen that I have provided a device in which oil is supplied to the rubbing bar as soon as the animal begins to rub against it, but in which the supply of oil is cut ofi after'a few drops have been discharged, no matter how long the animal continues to rub, and in which the parts return to their normal position as soon as the ani mal moves away from the device.

I claim 1. A hog oiler comprising a supporting bracket, a rubbing bar pivoted at its upper end to the bracket, guides on the bracket for the rubbing bar, a stop on the rubbing bar adapted to engage the bracket to limit the movement of the bar, a spring interposed between the bracket and rubbing bar, an oil trough pivotally mounted on the bracket above and in rear of the rubbing bar and having a discharge spout, an oil guideway on the rubbing bar, an oil reservoir above the oil trough having a spout discharging into the oil trough, a weighted lever pivoted to the bracket and having a finger on its upper end adapted to first en gage and then disengage the oil trough and a finger on the rubbing bar adapted to press against the said lever.

2. The combination in a hog oiler of a pivotally suspended oil trough having a discharge spout, an oil. reservoir above the oil trough having a spout discharging into the trough, a pivotally mounted rubbing bar and a movable finger adapted when moved rearwardly to first engage and then move beyond the oil trough to tilt the same and then allow it to return to normal position, the said finger being so moved by a rearward movement of the rubbing bar.

3. The combination in a hog oiler of a pivotally suspended oil trough having a dis charge spout on one side, a swinging rubbing bar having a curved lip near the top extending rearwardly below the above mentioned discharge spout, and means actuated by the rubbing bar for tilting the oil trough.

l. The combination in a hog oiler of a pivotally suspended oil trough having a downwardly projecting lug on the bottom thereof, a lever pivoted below the trough and having a weight on its lower end and a finger on its upper end adapted to engage the lug 011 the trough, a swinging rubbing Gopies of this patent may be obtained for five cents each, by addressing the Washington, D. 0.

bar, and means actuated by the rubbing bar for moving the lever rearwardly to tilt the trough.

5. The combination in a hog oiler of a tilting oil trough, a weighted lever adapted when moved rearwardly to first engage and then move beyond the oil trough to tilt the same and then allow it to return to normal position, and a swinging rubbing bar having a rearwardly projecting finger adapted to press against the said lever to operate the same.

6. A hog oiler comprising a movable rub bing member, a tilting oil receptacle, a movable finger adapted when moved rear ardly to first engage and then move beyond the oil receptacle to tilt the same and then allow it to return to normal position, the said finger being so moved by a rearward movement of the rubbing member.

7. In an apparatus substantially as described, a tilting trough having at one side a discharge spout below the level of its other side, a movable member adapted to first engage and then move beyond the said trough, and means for actuating the said movable member.

8. The combination of a reservoir, a tilting discharge trough sealing the discharge of the reservoir, a movable member adapted to first engage and then move beyond the said discharge trough, and means for actuating the said movable member.

9. In an animal oiler, the combination of a rubbing bar, a tilting trough discharging thereto, and a movable member actuated by a rearward movement of the rubbing bar adapted to first engage and then move be yond the said tilting trough.

10. In a device of the character described, a rubbing bar, a tilting trough discharging thereto and an intermediate device between the bar and trough adapted to tilt the latter, said intermediate device having a limited movement independent of that of the bar.
